Ancient Yeast Reborn in Modern Beer

Trapped inside a Lebanese weevil covered in ancient Burmese amber, a tiny colony of bacteria and yeast has lain dormant for up to 45 million years. A decade ago Raul Cano, now a scientist at the California Polytechnic State University, drilled a tiny hole into the amber and extracted more than 2,000 different kinds of microscopic creatures.

Activating the ancient yeast, Cano now brews barrels (not bottles) of pale ale and German wheat beer through the Fossil Fuels Brewing Company.
